要約

When accessing Confluence after an upgrade, Confluence displays an HTTP 500 error on the landing page, along with the following message:

java.util.concurrent.CompletionException: com.atlassian.util.concurrent.LazyReference$InitializationException: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'tenantedTransactionManager' defined in class path resource [databaseSubsystemContext.xml]: Invocation of init method failed; nested exception is com.atlassian.util.concurrent.LazyReference$InitializationException: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'tenantedLocalSessionFactoryBean5' defined in class path resource [productionDatabaseContext.xml]: Invocation of init method failed; nested exception is io.atlassian.util.concurrent.LazyReference$InitializationException: net.sf.hibernate.HibernateException: Could not find datasource

環境

• Confluence Server or Data Center (any version) with a datasource connection to the database.

診断

Checking the <confluence-home>/logs/atlassian-confluence.log file, the following error can be found:

2020-09-01 15:05:11,945 ERROR [Catalina-utility-1] [sf.hibernate.connection.DatasourceConnectionProvider] configure Could not find datasource: java:comp/env/jdbc/confluence
javax.naming.NameNotFoundException: Name [jdbc/confluence] is not bound in this Context. Unable to find [jdbc].

This indicates that Confluence was unable to establish a database connection while the application was being started, as the datasource connection configuration could not be found.

原因

When upgrading Confluence via the installer method, the installer will replace all files from the Confluence installation directory, and many customizations and settings from the previous installation files may need to be re-added, as stated in our Upgrading Confluence guide.

This includes the datasource connection definitions, which are stored inside the <confluence-install>/conf/server.xml file. As such, since the datasource connection definitions are not present on the new server.xml file following the Confluence upgrade, Confluence will not be able to find the necessary connection details in order to establish a database connection.

ソリューション

Edit the server.xml file from the upgraded Confluence instance, and add back the same datasource connection details that were present before the upgrade. After that, Confluence can be started, and it will be able to locate the connection details once again.
